LUCKING DEVICE FOR LEVERSI manner.

To aliwitom, it may concerw:

Be it known that 1,.Gnnsn C. Jensen, a citizen of the United States, residing at U ahland, in the county of Alameda and Stateof' California, have invented certain new and useful Improvements in Looking Devices for Levers, of which the following is a specifica tion. i

The present invention relates to locking devices for levers, particularly designed for use in connection with the variable speed power transmitting mechanism of a motor vehicle, and has for its principal objects to provide a simple and.eflicient loclnng means for levers or the described type, which is capable of being constructed at little cost and one consisting of but few parts.

llhe invention consists broadly in a bolt. or member connected to the lever and slidably mounted in a guide and cotiperating with which is a locking member for engaging the same to prevent. llneal movement of the bolt withinits. guide and thus lock the lever from operative movement.-

To more fully comprehend the invention,

reference is directed to the accompanying drawings, wherein- Figure 1 is a vertical sectional view of the preferred embodiment or my invention.

Fig. 2 is'a transverse sectional view taken on line 2-'2 of Fig. 1.

Referring more particularly to the several 1 views of the drawings, whereinlike charactersof reference deslgnate corresponding parts, 1 indicates a suitable housing formed in its top wall 2 with a vertical opening 3, through which extends the lever 4h. The.

lever is formed intermediate of its length with a spherical portion 5 for seating in a spherical socket 6 formed in the inner wall suriiaceot' the opening 3, thus providing a socket for the lever, wherein the same is capable of universal swinging movement.

7 'i-A. suitable ring 7 is adaptedto retain the. lever in its socket 6 in'the housmg.

.lPivotally connected, as at 7', to that portion of the lever 4 within the housing 1 is a bolt 8 adapted to lie at right angles to the lever and arranged in parallel spaced relation to the underside of the top wall 2 of the housing 1. The bolt is received at its free end within a suitable pocket or recess 9 formed in the housing- 1 which-provides a guide therefor. A suitabl Specification of Letters Patent.

same contacts with the walls of said pocket,

providing a sliding fit for the bolt when moved longitudinally and oscillated therein during the movementot the lever. The free i end, of said bolt 8 is provided with a vertlcally disposed transversely extending slot 11, the inner walls of which are formed with oppositely disposed semi-circular recesses 12' to recelve the walls of a cylindrical locking tumbler 13 extending perpendicular through the recess 9 and bearing at its lower end, as at 14, in a socket 15f 'lhe tumbler is provided on its opposite sides with flat faces 15 providing a portion thereof of a Width slightly less than that of the slot 11, thus permltting lineal movement of the locking bolt on the alining of the flat f faces 15 with the side Walls of the slot 11. llhe tumbler l3 depends from the underside of a cup 16 rotatably mounted in a seat 1'? in the housing top wall 2 and within a, seat 1'? 1n sald cup 1s positioned a lock-casing 1'8 1 carrying a rotatable key controlled barrel 19,

aportion 19 of which is disposed eccentrically. thereof and projects below the same and into the transverse bore 20 formed in the cup 16.v

' Mounted in the bore 20 and slidable transversely of the cup is a'locking pin 21 having a recess 22 in its upper surface into which rel l9. p

A spring 23 positioned in a suitable projects the eccentric'portion 19' of the barchamber in the cup 16 bears against a lug 2t on the underside of the pin 21 and forces the same outwardly against the action of the v eccentric portion 19 of the barrel 19.

When the parts are positioned as in the drawing, with the locking pawl precluding 9e.

longitudinal movement of the locking bolt and operative movement of the lever, the end of the locking pin 21 is received in a depree-= sion 24' in' the side wall of the seat 1'7, and is removed therefromby a slight rotation of the key operated barrel 19, which causes the eccentric portion 19 thereof to move the locking pin 21 lineally until the'rear end thereof contacts'with the wall of said seat 17,.t1t which time further-rotation of the barrel eauses a'rotation of the cup 16 and tumbler'13 until such time as the flat faces 15 of the tumbler aline with the races of. the slot 11, releasing the locking bolt toper- 'llhe rotation rnit operation of the lever. of the cup and barrel to loch the lever from movement is preferably accomplished.
